SAWING ANI) TRIMMING ELIACHINE.

Application filed February 18, 1922. Serial No. 537,542.

To aZ'Z whom it may] concern:

Be it known that I. IVALTER RUNNELs, a citizen of the United States,residing at the city and county of Kalamazoo, State of Michigan, haveinvented certain new and useful Improvements in Sawing and TrimmingMachines, of which the following is a specification.

This invention relates to improvements in sawing and trimming machines.

My improved sawing and trimming machine is especially designed by me foruse in sawing and trimming electrotypes, stereotypes, linotypes,halftones and the like, and performing other operations thereon, and Ihave illustrated my improvementsas I have embodied the same in a machineforthar purpose, certain features of my improvements are, however,adapted and desirable for use in machines designed for other work.

The main objects of the invention are r First, to provide a machine ofthe class described which is adapted to readily perform variousoperations in thefitting of electrotypes, linotypes and the like.

Second, to provide a structure ofthe class described which is veryrapidly manipu lated to securethe work and to perform the desiredoperations.

Third, to provide in a machine of the class described an improve'd workholding machine adapted for quick manipulation to secure or release thework.

Fourth, to provide in a structure of the class described an improvedmeans for undercutting and gaging undercuts.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribedin the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention isclearlyillustrated in the accompanying drawing, forming a part of thisapplication, in which: v Fig. I is a righthand side elevation of myimproved sawing and trimming machine, the saline being adjusted toinoperative position and the saw guard being shown open or ininoperative position.

In the drawing similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the base 1 i of suitable size to receive thepedestal 2'having a table 3 mounted thereon, The pedestal has arearwardly projecting bracket 4 having an angled arm or head 5 mountedthereon to overhang the rear portion of the table.- The table has anopening 6 therein through which the saw may be swung to and from thework. The saw hanger or arm is mounted below the table on the rock shaft8, so that the saw 9 ca ed thereb may be swung through the opening 6.-The arbor 1O of the saw 9 is mounted on the outer the lever having asegmental slot 21 therein engaged by the clamping pin 22 for securingthe arm 7 in its adjusted position, this pin being carried by thebracket on the under side of the table, the rock shaft being mounted onthe bracket. With this arrangement of parts the saw 111 be usted toperform the desired worn hout affecting its driving connections. I

The belt 18 is provided with a tightener pulley 24. The opening 6 isprovided with a cover 25 which is adapted to close the o ing when thecover is dropped down to inoperative position. This cover is supportedabove the saw by .means of the gage, designated generally by the numeral28, mounted on the saw hanger. This comprises a gage screw 27 disposedthrough the barrel 28 mounted on the arm 7. The screw is provided withan indicia disk 29 mounted upon a block 30 pinned to the screw, theindicia member being frictionally held on the block by means of thespring 31. A pointer 32 is mounted upon the supporting barrel of thegage to coact with the index. The gage normally serves to support thecover when the saw is swung to operative position and it also serves asa gaging means for securing under cuts, the method of operation forsecuring such unoer cuts being as follows:

First, adjust the saw to a to four points above the table;

Second, adjust screw 27 by 'reans of the knob on the lower end until itprojects about one inch or 6 picas above the dial or inclicia disk 29; 5

Third, loosen the set screw and adjust the complete gauge unit until itstrikes the cover 25 and then look in position Fourth, hold the cover bymeans of a flat object such as the smooth side of a linotype slug andadjust screw 27 until the cover is level with the top of the saw eeth;

Fifth, raise the cover and, holding the screw from turning, move thedial to the zero mark;

SiXth,'turn the adjusting screw to left, each full turn of the dialequaling six points;

Seventh, hold the cover with one hand raising the saw as far as possiblewithout position two (printers measurement) raising the cover above thelevel of the table and lock the saw in position.

The arbor is also preferably provided with a grinding wheel 34. A sawguard 35 is pivoted at 36 at the rear end of the table to be swung outof operative position, as shown in Fig. I, leaving the top of the tableclear or to be swung forwardly, resting upon the cover 25, as shown inFig. I

I will'now describe the workholder and won: gaging means. This comprisesa slide or carriage 37 resting upon the top of the table and guidedthereon by the groove 38, this carriage having a guiding slide travelingin the groove. A bar is mounted on the front edge of the carriage.micrometer or gage screw 41 is mounted on this bar and provided with anadjusting hand wheel 42. The screw is provided with a micrometer screwor gaging dial as. The gage finger or member i-i rests upon the table infront of the carriage and is provided with a yoke 45 embracing the bar40 and'the screw l1 and carrying a. half nut 46 coacting with the screw.This nut is held yieldingly in engagement with the screw by means of thecoiled spring 47. A pin 48 provided with a handpiece 41-9 is connectedto the half nut 46 so that it may be lifted against the tension of thespring iii) and, by giving it a. half turn, the pins or lugs 50 arewithdrawn from notches provided in the top of the yoke so, that the lugsrest upon the yoke holding the parts in elevated position, as shown indotted lines in Fig. X, thereby permitting the rapid adjustment of thegage member to the work.

A scale 51 is provided on the carriage for quickadjustment or roughadjustment purposes, the yoke of the gage member 44 being provided witha pointer 52 coacting with this scale 51. This allows the rapidadjustment, as stated, when the nut is disengaged by sliding the gagemember on the table and final accurate adjustment through means of thescrew 41. c

The yoke 45 has a pair of singularly disposed pins 53 which engage thegroove 54 in the rear edge of the bar 40, thus holding the yoke inposition. To permit convenient engaging and releasing of the gage memberthe wall of the groove is provided with notches 55 near the outer end ofthe bar so that the gage member can be adjusted to register the pinswith these slots or notches and the yoke lifted from or engaged with thebar.

To prevent the accidental withdrawal of the carriage from the table, Iprovide the table with a stop 56 with which the projecting end of thebar 10 is adapted to engage when the carriage is in its fully retractedposition.

The work gage is provided with a removable bar 57 which I designate astwelve ill) point attacheinent, theface of the work gage or holder beingrabbeted at 58 to receive this removable bar, the outer face of which isflush with, the face of the work Pins 59 hold this twelve point attachment to the gage member. By this connection the bar 57 can bereadily removed by lifting upwardly but when, in position is properlysupported to receive the work. lVhen this bar 57 is removed theprojecting bottom. portion 60 of the gage member will project under thework clamping bar 61, which permits the clamping and sawing of work asshort as one pica or .166 of an inch.

The work clamping bar 61 is slidably mounted on the forwardly projectingarm 62 on the work carriage 37. The work clamping bar is adjusted bymeans of the clamping rod 63 having a screw portion 6st. This rod issupported by a guide 65 on the arm 62 and a support 66 on the carriage.A split clamping nut 67 is providedfor securing this rod in its adjustedposition, the nut being provided with a linger-piece 68, its split endcoacting with the support 66 to engage the nut. This work clamp is thatshown in my Letters Patent No. 1,408,831 dated March 7, 1922.

To secure lefthand miter cuts 1 provide a vise or work holder member 69of triangular shape adapted to seat against the work gage 141. This workholder is pro vided with a clamping member 70 secured in its adjustedpositions by clamping screw 71 at the outer end of the work holder.72,see Fig. XV, indicates wor r within the holder. The side or face 73of this angle cutting work holder is at anangle of 15 and is providedwith a scale 74: for the gage block 75. A series of holes 76 are adaptedto receive a pin on the gage block, the pin not being illustrated, sothat the gage block may be adjusted to the desired position.

lVith the work thus supported it is presented to the saw at a 45 angle.

1 also 'PIOVIdQ what I designate as a righthand miter work holder,seeFigs. V and XI. The rear right-hand corner of the work carriage 1sbeveled or planed oil at an angle of 15 at 77 and adapted to receive thearm 78 of the work clamp or holder 79, so that the work may be clampedbetween the face 77 of the work holder and the opposing face 80 of theclamp,see Fig. XI. A clamping nut 81 is provided forthe work holder 79.A piece of work may thus be clamped at an angle of 415 to secure arighthand miter.

I also provide what I designate as a batter gage 82 which is slidablysupported in the bracket 83 mounted on the'table opposite the workholder. This bracket'is preferably 'detachably mounted so that ifdesired. it may be removed to clear ther-face-of the table. The battergage has a stem 84 arranged through the bracket 83 and adjustablysecured therein by means of a set screw This is of particular advantagein gaging ranged to co-operate nth both the leftand right hand miters,the batter gage being set and the work for both right and left handmiters being placed in the holders therefor with their ends against thegage Thisenables the turning of both miters at the same time and greatlyfacilitates the work. It also may used for squaring linotype blocks andthe like, the blocks being laid against the and fed into the saw, or iti;

may be used to square up the ends of sev eral blocks or to tap the workinto alignment. Other uses will be foundin the practical operation ofthe machine.

The overhanging arm or head 5 is formed separately from the arm 4': ofthe pedestal and is mounted thereon by means of the'king or pivot bolt86 and the screws 87. This holds the head rigidly in place.

However, by removing the screws 87 the head 5-can be swung to one sideofthe table, leaving its top entirely free. The head is of an Icrossseetien, that is, it has flanges 88 projecting at each side of itscentral web 89, thus providing housings for parts carried by the head.These parts are a jigsaw, drill and router mechanism. The jig sawplunger 90 is supported in a guide 91 on the lefthand side of thepedestal. This plunger is connected to the lower end of the saw blade92, the upper end of the blade being connected to the retracting plunger93, which is connected to the retracting spring 94: through the lever 95pivoted at 96 and connected to the plunger 93 by the link 97. Theplunger 93 is mounted in the guides 98 on the head and the spring andlever described are housed within the lefthand channel of the head. Theplunger 90 is connected by the pitman 99 to the crank wheel 100, whichis connected to the shaft 16 by the belt 101. A guide 93 is provided forthe saw blade engaging saw in a spaced relation to the surface of thetable on which the work rests. dle 102 is provided with a chuck 103.This spindle is mounted in a bearing 104 disposed in the righthandchannel of the head,see Figs. T, VT and VII. The spindle is providedwith apulley 105 connected by the belt 106 to a pulley 107 disposed atthe rear angle of the head, the pulley 107 being connected by a belt 108to a pulley 109 mounted on the bracket 4 of the pedestal, and thispulley 109 connected by the belt 110 to a pulley on the shaft 16, thepulley on the shaft 16 not being illustrated.

p The spindle 102 is carried by a sleeve 111 having a rack on one sidethereof with which the gear 112- on the bearing member 1042 pieces to bemitered and is ar- The drill and router spin-' meshes. This gear 112 isdriven through the sprocket chain 113, one end of which is connected tothe coiled spring 114: secured to the head at 115, and the other end tocable 116 disposed over the guide pulleys 117 and 118 ahd connected tothe foot lei 11.9 pivoted on the base at 120.

Vith this arrangement a downward movement of the end of the lever feedsthe spindle downwardly. To limit the stroke of the spindle E provide ascrew 121 carried by the bearing member and having stop nuts 122 and 123thereon adapted to coact with the stoo member 12* on the sleeve 111.These drill spindle parts and driving and feed connections therefor aremainl -J housed within the righthand channel of the head.

The sawdust or discharge pipe 0 conduit 125 is disposed on the righthandside of the pedestal with its upper end in proper relation to thesaw.see I. The shaft portion of the pedestal is also of I cross sectionand serves as a housing for certain operating parts and partially housesthis conduit,-
